Question

So my questions are: Rewrite each

Answer 1

We are given expression: $4^{-1}$

We need to write the expression without negative exponents.

We need to convert it in positive exponents.

We know the rule of negative exponents as following:

$a^{-n} = \frac{1}{a^n}$

On applying same rule, the 4 would go in the bottom of 1.

$4^{-1} = \frac{1}{4^1}$

We know 4^1 = 4.

Therefore,

$\frac{1}{4^1} = \frac{1}{4}$
